BOTTLE AND CA1P THEREFOR Application led `October 22.1931. Serial N o.570,282.

This invention relates to an improvement in bottles and caps thereforand .consists in the novel rconstructionhereinafter disclosed.

Anobject of this 'invention isto provide a'bottle cap incombinationwitha specially formed bottle neck which is adapted to bereadily applied to close the bottle and seal the neck together withmeans for preventing unauthorized contamination with vthe bottleclosure. Y

Another object of this invention isto pro'- vide in combination with theneck of a bottle a removable cap that may be adj usted on the neck' ofthe bottle to eiect a positive closure thereof and which may be removedwithout damage to thecap. y

More specifically an object of the invention is to provide a bottle witha specially orni'ed neck in combination with .a cap4 having -a cuppedcap portion adapted toieceive'a'sealing washer, the cap being provided"with an elastic apron formed from spaced Vtongues in which a speciallyformed ybinding ring [is mounted, together with a leverv` associatedwith the binding ring to tightly -clamp the cap in position and thelever being so'torined and associated with the other parts as that itmay -be sealed against unauthorized movement by a destructiblesealing'band.

Additional advantagesoic the construction will be readily apparent fromthe following detail description thereof taken in 'connection with theaccompanying drawings, in which-.- n Fig. l is a topplan view of thebottle cap.

In the embodiment ofthe Ainvention* illustrated in the drawings theinvention is shown as environed in abottle particularly adapted for useas a, container for lubricating oil. It liasbecome 'an establishedpractice in merchandising lubricating oil to dispense it from containersfilled at a common point and the seal of which is'broken only at thetime the oil is'delivered to customers. The common practice has been toapply caps of'usual con,- struction that are forcedfromtheneck of thebottle and the cap, therefore, destroyed when the contents of the bottleare dispensed.

The purpose of ythe kdestruction of the caps may be as'readilyaccomplished by providing a destructible seal that is required to Abebroken before the removal of the cap but allowing ythecap to be removedwithout distortion so that it maybe re-used ywhen the container isrelilled. Furthermore itis an advantage to immediately replace the capon the bottle after the contents have been dispensed soy that inrefilling the bottle it is un necessary to wash themas the'iinmediatereplacement of the cap will prevent the content of the bottlesfrom beingcontaminated by dustor dirt entering the neck of the bottle when thecap` is entirely removed and not replaced.v Itis also necessary onaccount oi' the required cleanliness in distribution of the lubricatingoil that the cap tightly seal the bottle when in place.

An object ofthe invention is to provide a bottle especially adapted`fory the purposes outlined although it will, ofcourse, be understoodthat the use of the cap and bottle are not limited to these specicpurposes.

In the embodiment of the invention illustrated in the drawings thebottle 1 is shown as including a specially formed neck 2 which isprovided with an annular bead 3 around the bottle opening and a bead 4around the neck of the bottle and at a space somewhat below the bead 3,thereby forming an intermediate circular section 5 of the bottle neck.The er adjusted over the bottle mouth and the edge of the bead 3. Thearms 7 are equally spaced exce t at the rear of the cap as shown in Fig.4. gne of the arms 7 is omitted at each side of the center line to formenlarged spaced openings 9, and at the front of the cap, as shown inFig. 2, a plurality of the arms are omitted to provide an enlargedspaced opening 10. The head of the cap is adapted to receive interiorlythereof a washer 11 of any suitable sealing material such as preparedcork, fiber, or the like. Thus when the cap is fitted on the bottle neckthe washerwill be positioned over the upper edge of the bottle opening.A continuous binding ring, preferably in the form of an annular wire 12,is mounted in the eyes 8, the eyes bein formed by turning the lowerextremity of t e arm 7 over the wire. The wire is provided with upwardlyand inwardly deflected portions 13 in the segments of the wire thatunderlie the enlarged spaces 9 in the apron of the cap. These segmentsof the wire, when the cap is in position, extend into the shoulderformed by the face of the bottle neck and the bottom wall of the bead 3and constitute spring bearing points against the bead 3. Mounted on thatsegment of the wire 12 that underlies the enlarged space 10 of thebottle cap apron is a lever 14, said lever including an outward convexsection 15 and side flanges 16, the body of the lever thus formedmerging into an outwardly deflected finger piece 17. The upper edge ofthe lever, when the lever is in adjusted position, is defiectedoutwardly slightly, as indicated at 18, Fig. 5, so that it engages underthe shoulder formed between the face of the ybottle neck and the lowerface of the bead. The lever is mounted on the binding ringrearwardly ofthe ring by passing the ring through ears 19 formed in extension of theflanges 16. That segment of the ring that underlies the cutout section10 is somewhat fiattened as indicated at 20, Fig. 6. Thus when the capis placed on the bottle neck and the lever swung downwardly to anadjusted position the outwardly extending edge 18 of the lever engagesunder the bead 3 after the lever has passed over center thereby forcingthe portions 13 of the ring into closecontact with the bead and engagingthe bead at the front of the bottle cap along the upper edge of thelever. The inwardly defiected portion of the ring 20 bearing against thefront face of the lever relieves the bearing of the ring on the ears 19.When the lever is thus operated it forces the entire cap downwardly andcompresses the gasket 11 holding the parts in tightly sealed adjustment.

The ring 10 is secured to the arms 7 that lie between the spaces 9 atthe rear ofthe cap but the ring is free to move in the eyes beyond thespaces 9. Thus as the lever is depressed the flat portion 20 ofthe. ringis forced outwardly exerting a circumferential pull on the segment ofthe ring lying in the long direction between the portions 13 thereof.This permits the upper edge of the lever to find its seat against thebead 3 and the portion 20 of the ring then presses against the frontface of the lever holding the upper edge of the lever rmly in placeagainst the bead 3.

After the cap has been adjusted the lever is held against unauthorizedmanipulation by a destructible band seal 21 fastened about the neck ofthe bottle and across the face of the lever. It should be noted that thelever 14 is provided with a flat section intermediate the beads 3 and 4and that the portion of the lever that extends below the bead 4 isdeflected so that it rests flat against the face of the bottle neck andthe face of the bead 4. That portion of the lever lying between thebeads 3 and 4, when the lever is in assembled position, is encompassedby the destructible seal and since it is not possible to remove the capwithout raising the lever to disengage the upper edge thereof from thebead, the cap cannot be removed without breaking the seal.

I am aware that the invention may be modified, in numerous particulars,without departing from the spirit and scope of the invention. I do notlimit myself, therefore, to the specific constructions shown and described, but what T claim and desire to secure by Letters Patent is:
